Conventions

• Frontmatter — every note has tags and aliases where applicable
• Wikilinks — [[Note Name]] used throughout; aliases allow linking by alternate names
• Callouts — [!info], [!tip], [!warning], [!note] used to highlight key information
• Tag taxonomy — #ai-agents #ml #algorithms #dsa #system-design #lld #golang #security #owasp #aws #book #course

The System Design section is the reference standard for note quality in this vault.
